The Allen-Bradley 1794-TB3G Flex I/O Terminal Base Unit is a grounded screw-clamp docking interface used in Flex I/O distributed control systems. It serves as the physical and electrical connection point between field wiring and I/O modules.
By separating wiring from the I/O module itself, the system allows fast replacement of modules without disturbing field wiring. This reduces downtime and simplifies maintenance in industrial environments.
The 1794-TB3G is commonly used in applications requiring reliable grounding, modular expansion, and flexible I/O configurations in distributed automation systems.
